To all whom it may concern:

Be it known that l, LUTHER @.BALDWIN, of Manchester, in thecounty of Hillsborough and State of Kew Hampshire` have invented certain new and useful Improvements in Apparatus for Painting and Drying Bobbins and other Articles, of which the following is afull, clear, and exact description.

This invention, while it may be used for painting and drying handles of different kinds and varionsother articles, is more especially intended for painting and drying spinningrnachine bobbins, which require to be painted on their ends, and the invention will here be described more particularly with reference to such use. Its object is in part the same as that of the apparatus for drying bobbins secured to ine by Letters Patent No. 237,074C on January 25, 1881, and it resembles said apparatus to the extent that the bobbins have a prolonged travel on an endless moving belt, to give them an opportunity of drying after be- 4ing painted without laying them on boards for the purpose, andwhcreby they are collected without handling or attention; but the invention essentiallydilfers from said apparatus in several important respects, and not only is designed `for drying bobbins, but also for painting them; and it consists in a novel arrangement of the belt or belts by which the bobbins are carried and traversed, whereby a prolonged travel is obtained for them in avery contracted space; also, novel means for plac ing and delivering the bobbins, and for painting, or guiding, steadying, and rotating them while being painted, substantially as hereinafter described.

Reference is to be had to the accompanying drawings, .forming part of this specification, in which similar letters of reference indicate corresponding parts in all the igures.

Figure l represents a front elevation of my improved apparatus. Fig. 2 is avertical section of the saine, upon a larger scale, mainly on the line a: .as in Fig. 1. Fig. 3 is a further vertical section in part, upon a still larger scale, onthe line y y in Fig. l; and Fig. 4, a vertical longitudinal section of a device for rotating, guiding, and steadying the bobbins while being painted.

The apparatus represented in the drawings is a double one-that is, it is constructed to provide for giving the bobbins or articles to be painted a second coat of paint, and intermediately and subsequently drying them; but the appartus may be a single one-that is, be constructed to apply only one coat of paint.

A is the endless belt,\vhich is made of ilexible material, and is arranged to run in a series of any number (more than two) of closely disposed forward and backward paths-#one above the other-and downward to the deliv ery device. A

The apparatus represented in the drawings being a double one, two tiers, B B, arranged side by side of such forward and backward runs for the belt, are shown in Fig. 1, the arrows e indicating the course of its travel. Said belt is supported on rollers c a, to which power will be applied in any convenient manl ner to give a slow continuons movement ofthe belt around the rollers. The rollers a o; are sustained ina frame or supports of any snitable kind.

Secured crosswisc upon the belt A, and so as to project from the front edge of it, are spindles or mandrels Z1 b, forming carriers for the bobbins c c, lor articles to be painted and dried. Said mandrels may, if desired, be secured in sockets ou the belt, so as to be capable of rotating, instead of the bobbins c c rotating upon them, as hereinafter described. These mandrels b b may be arranged only at such distances apart throughout the length of the belt to receive overtheni thebobbins without touching one another.

D is aflxed lower receiving stand or guide behind or longitudinally through a way or slot, d, in which (that may or may not be fitted with guide-rollers) the belt A travels, said way being set inclining upward toward the front of the stand, as shown in Fig. 3, and the belt being deflected to correspond as it passestherethrough, in order that the mandrels b b may incline forwardly in an upward direction, to kfacilitate the placing of the bobbins c c on them. The deflection of the beltshould be gradual as vit enters and leaves the stand D.

The articles or bobbins c c to be vpainted and dried are slipped on and over the mandrels bb as they pass with the belt through the stand D, and are carried by the belt A first IOO along their lower line of travel in the tier B of successive forward and backward belt-paths, separated by guide-strips e, to and over a righthand rotary paint-brush, E, that may be driven by pulleyS f y, and which is supplied with paint from a receptacle, 7L, arranged to receive the lower portion of the. brush withinit. Said bobbins c c, as they pass with the belt A over the brush E, are rotated', so as to present the whole circumferential portion of their ends to the action of the brush, to secure their being thoroughly painted. This may be done either by fitting the bobbins c c tightly on the mandrels b b, and rotating said mandrels by any suitable gear at their back ends, or, as here shown, it may be done by two short upper and lower endless friction-belts, G G, supported by end rollers, i, and intermediate blocks, 7c, or otherwise, and arranged to receive' between them the body portions of the bobbins c c, fitted loosely on the mandrels b b, said belts G G being driven by any suitable gear applied to their end rollers, or certain of them, and so causing the bobbins c c to be rapidly rotated as they pass over the brush, for the purpose hereinbefore stated. Such bobbilrrotating device also serves to guide and steady the rotating bobbins as they pass over thebrush, and

for this purpose, and to prevent the frictionbelts G G from flexing out of contact with the bobbins, the running portions of said belts, which bear against the bobbins, are supported by a series of rollers or other supports, ZZ, arranged within the belts in interposed relation with each oth'er in the one belt relatively to the other, as shown in Fig. 4. 'Ihe bobbins c c, having been thus painted on their ends, are carried backward and forward along the different belt-paths throughout the tier B of such courses of travel of the belt A, for the purpose of drying the painted bobbins, and afterward, if the apparatus be a single one, are conveyed by said belt A down to the delivery devices; but when the apparatus is a double one, as shown in Fig. 1,'the painted and partially or wholly dried bobbins c c, after leaving the tier B of the belts courses of travel, are passed along and overhead and down to the bottom of another and corresponding tier, B, of forward and backward pathways for the belt before conveying them to the delivery devices. This is for the purpose of giving the bobbins c c a second coat of paint, or of varnishing them, by causing said bobbins to pass and be rotated, by means as hereinbefore described for the tier B, over a second brush, E, in or applied to the tier B, and afterward, by the continued backward and forward travel of the belt A, of drying the bob= bins. As the belt A leaves its upper course of travel in the tier B, it passes down on the inner end of said tier to the delivery device or devices, which are here shown as consisting of two parallel rods, II II, set inclining forward in a downward direction, and arranged so that while the mandrels b b pass down in between them, the back ends of the bobbins travel down over them, whereby said rods or inclines, acting as an ejector, cause the bobbins c c to be forced from ofi' the mandrels, as

shown in Fig. 2, and to be delivered through 7o a spout, I, into any suitable receptacle,where they are collected without any further handling or attention. y In this way or by these means provision is made for rapidly and automatically painting and drying the bobbins,

and the arrangement of the belt which carries 'them secures a prolonged travel and thorough drying of them in large quantities in a very small space or compass. Any suitable registering mechanism may be used, if desired, in connection with the apparatus, for registering the number of bobbins or articles passing through it.

Having thus described my invention, what I claim as new, and desire to secureby Letters Patent, is

l. In an apparatus for painting and drying bobbins and other like articles, the traveling endless belt provided with work carrying spindles or mandrels, and arranged to form one or more vertical tiers of forward and backward horizontal courses of travel, substantially as specified.
